When feeding black soldier fly larvae to little chicks, we're more careful about how much larvae to feed them. For bigger chicks, they'll do fine with big & small larvae. Actually your girls & guys will come running for these little treats. Let's see some ideas for how to feed them yummy BSF grubs.
Feeding BSF to little chicks
For chicks about 7-10 days old, people usually throw in some little BSF larvae in their feeding area. 5- or 7-days-old larvae are good for the little chicks because they are small so it's easier for them to chew. People feed the chicks this early so they can get used to the smell & taste.
What we should look out for is too much protein. Although the BSF larvae contain a good amount of protein, we don't want too much yet for the baby chicks. An excess amount of protein may cause diarrhea or the chicks may excrete white poop. To help their young digestive system, mix in some little pebbles to make the foods easier to digest.
For chicks from 1 to 21 days old, we can combine:
- 1/3 BSF larvae
- 1/3 greens
- 1/3 seeds or grains
Using this ratio, you can feed them once a day. That'll be good enough at this stage. It's safer to filter out the poop of the larvae before feeding the chicks.
For 2-days-old larvae, the poop can be difficult to screen out. But for 5-days-old or older bigger larvae, this task is easier. If the feeding substrate is wet, you can wait several days for the substrate to dry & add no more water to it before harvesting the larvae. After 3-4 days, as the substrate dries you can use a sifter to sieve the remaining crumbled pieces out. Alternatively, you can run the larvae under running water to wash off any remaining frass around their bodies.
Some people add digestive enzymes to help the young chicks digestion. It's good to feed them in the morning & less in the evening.
Feeding BSF grubs to bigger chickens
Bigger chickens from day 21 & older have no problems chewing BSF larvae. They actually love this stuff. People find that when you start feeding the chickens with these larvae, they actually turn 'nah thanks' to the pre-made chicken feed. Putting them side by side, the chickens will naturally gravitate towards the BSF larvae.
If you have around 60-70 chickens, then mixing this amount of larvae will be good enough for them:
- 3 kg BSF larvae
- 1/3 greens
- 1/3 grains
So the question many folks ask is why not feed them 100% BSF larvae? A diet with 100% larvae may give the chickens too much protein than what their bodies need. Because one BSF larvae contains nearly 40-45% protein. Especially if you use 15-days-old larvae that have turned a bit black. Those guys at that stage pack the max amount of nutrients inside them. So it's like a dynamite of protein.
Raising chickens for eggs
If you're raising chickens for eggs, then too much protein will make them fat. When chickens are overly fat, they won't lay eggs as early. So for egg chickens, supplementing about 3% of larvae in their diet will be good enough for them. With the calcium in the larvae, the eggs laid will have very strong shells. Their yolks have a deep orange color & are not easy to break loose.
This is the same with quails. If you feed them 3-4 times/day with 100% BSF larvae, their reproduction system may get blocked. So we can balance out the diet with some cornmeal, greens or soybean meal to give them the starch, vitamins & fibers they need.
Raising chickens for meat
If you're raising chickens for meat, then 40-70% of BSF larvae in their diet will be nice. The chitin stuff in the exoskeleton of the larvae helps build the chicken muscles & lowers the fat amount. The chickens will develop extremely beautiful, smooth feathers. This lowers the risk of them poking into each other or the feathers falling off here and there. Their immune system can get stronger. We then can worry less about their health & money spent on probiotics.
For the most careful farmers, they pre-treat the larvae with microbial enzymes. This helps eat off any potentially harmful bacteria around the BSF larvae before the grubs get to the chickens. If you have the rinds of mangosteen or guava leaves, try cooking those up and dilute them with water (to reduce the tartness). Add a bit of honey or sugar to make it easier for the chickens to drink. Give them some of the drink every morning. This stuff will keep their stomach strong & happy.

General-purpose BSF feeding recipes for chicks
Here are some general-purpose feeding recipes for the chickens:
1 month old
A bit more chicken feed at this point + supplementary small BSF larvae to help their young digestive system & avoid protein overload.
2 month old
- 5 kg/11 lbs corn
- 5 kg/11 lbs bran
- 8 kg/17 lbs BSF larvae
3 month old
- 5 kg BSF larvae + other grains and greens
Hope this brief post has given you some ideas for feeding BSF larvae to the chicks. Good luck & have fun with watching your flock grow strong and joyful.
